    At what water temperature does the engine overheat light go on in a 6.2 diesel engine? How is the temperature sensor calibrated?

    As far as I know, my 83 isn't equipped with such a light. Maybe it is but I've never had a chance to see it in action(Thank God /forums/images/icons/smirk.gif ).

    The only warning I have related to the cooling system(other than my temp gauge) is a "Low Coolant" light below the speedometer. I'm not sure where the sensor is or what it reads, but it has to be either actual coolant level or maybe system pressure. It used to come on sporadically and everytime I checked the system was full to the top.

    Anyhow, enough sidetracking. Sorry I couldn't be more help. If you find out anything else keep us posted. I'd be curious to find out more about it.

    I have an 83 and am yet to see an overheat light. There is a low coolant light. The sensor is located inside the radiator. There is a wire on the outside passenger side of the radiator.

    I am sure Piotr have an Ex-Army model. They have warning lamps instead gauges. Rumors maintain, soldiers cannot read. Sorry Diesel Dan.
